SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 439,623, dated November 4, 1890,

Application filed May 28, 1889. Serial Nox 312,383. (Model.)

T0 all whom t may concern:

Be it known that I, WILLIAM FEssENDEN BEASLEY, a citizen of the United States, rcsiding at Oxford, in the county of Granville and State of North Carolina, have invented certain new and useful Improvements in Seal- Locks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in seal-locks; and it consists in the combination of a sliding bolt having a slot for the reception of the seal witha register, so that on each unlocking motion of the bolt the register is actuated, recording such mot-ion, and in details of construction thereof, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts are designated by corresponding letters, Figure l is a side view of my invention with the cover removed. Fig. 2 is a longitudinal central section thereof, the cover being on. Fig. 3 is a plan viewof a lock differing slightly from that shown in Figs. 1 and 2, but also of my invention, the cover thereof being removed. Fig. 4; is a detail perspective view of the sliding bolt. Fig. 5 is a detail perspective view of the dogs. Fig. G is a detail side view of the slide E. Fig. 7 is a cross section on line a: of Fig. 1, with the bolt removed.

The base-plate A has in its ends holes a to receive bolts, nails, tbc., for securing it in position, and has formed upon the central portion of its face longitudinal walls a Cthe said walls abutting at one end against the transverse wall a3, which is separated from a second transverse wall a4 bya channel a5, the said channel being adapted to receive a hasp of any suitable forni. 'l he opposite ends of the walls a a2 are contiguous to the shoulders a6 formed on either side of the plate A. The

second transverse wall d4 is provided with a recess al and serves as a keeper for the bolt.

The bolt B is provided on the forward end of its face with a handle l1 and a rib D', the latter having a slot b2 to receive the continuous ring c of the seal O. The lower surface of the bolt slides upon the face of the walls a a2, and has in the middle of its rear end a post b3, which slides in the channel as between the said walls a and a2, one face of the said projection having anotch b4 and beveled ends b5 and h6. A lug bl is also formed on the rear end of the lowersurface of the said bolt, but. on one side thereof, to actuate the register, as will be hereinafter described.

In a recess a9 formed in the longitudinal wall a are pivoted dogs D, the noses d of which project into the longitudinal channel as, being'normally held in that position by springs d. A slide E rests beside the wall a2 and has shoulders e e on its forward and rear end, respectively, being held in position by a screw c2 let into the plate A. Projecting from the rear end of the slide and attached thereto is a trip-lever c3, the free end of which is held against the cog-wheel f by means of a spring e4.

On the shaft F, carried by the shoulders a of the base-plate are a series of lwheels f, f', f2, and f3. Each of these wheels has impressed on a part of its periphery the successive numbers from O to E), inclusive, while a series of recesses ft, forming cogs, are placed in the remaining portion thereof, each recess being opposite a number. On the shaft G, also supported by the shoulders a of the base-plate, and which is parallel to the shaft F, are a series of gear-wheels g, g', and g2, separated from each other by sleeves g3 upon the shaft G. Each of the wheels g, tbc., has a crown-gearing formed by pins g", projecting from a face thereof, and a spur-gearing formed by a corresponding number of shoulders g5 on its periphery. The pins g* gear with the recesses f4 on the wheels f', f2, and f3, while the shoulders g5 are struck by pins f5, projecting from the sides of the wheels f, f', and f2, each of the said wheels having such a pin. A spring-catch f is attached to one of the shoulders a, and by engaging in the recess f* of the first wheel f prevents its backward rotation.

A cover II fits over the base-plate from the transverse wall ai to the opposite end thereof, covering the hereinbefore-described mechanism, and is provided with a slot 72 having a glass 7L', through which the state of the register may be taken. The operation of my device is as follows: The bolt B is first pushed IOO under the cover H as far as possible, as indicated in dotted lines in Fig. 2, thusV leaving the channel a5 open. The hasp is now inserted therein and the bolt withdrawn to its full extent. In so doing the forward beveled end b5 of the post b3 will strike the dogs D and throw them back into the recess a9, thus permitting the post to slide along the channel as to its forward end, after the passage of which the spring d will throw the nose of the dogs back into the channel behind the said post. The lug 57 will also strike the forward shoulder e of the slide E and draw the latter forward, the said parts now having the position shown in Figs. l and.6. The bolt is then shoved in or backward until it assumes the position shown in full lines in Fig. 2, and in so doing the lrear beveled end b of the post b3 will strikev the noses CZ of the dogs I), forcing them back to permit its partial passage; but the springs d will again throw them out, so that they engage the notch b4 in the post b3, as shown in Fig. 5. The dogs thus prevent a forward, but not a backward, movement of -the bolt, the latter being prevented by the ring c of the seal contained between the slot b2 of the bolt and the end of the cover I-I. If it is now desired to remove the hasp, it is necessary to shove backward the bolt, and this can only be done by breaking the ring c of the seal and removing it from the recess b2. As in some instances it may be possible for other seals to be obtained and inserted in lieu of the broken ones,thus leaving no traces of the lock having been tampered with, I provide the above-described recording device, which serves to record the unlocking, for as the bolt is shoved backward after the seal has been broken the lug 197 thereon will strikev the rear shoulder e of the slide E and thus carry the latter back with it. The rear end of the triplever e3 will then engage a recess f4 in the wheel f and move the latter one space forward, causing a correspondingly-higher number to appear under the slot h of the cover, by which means it may be readily ascertained Whether the deviceY has been unlocked between any two successive readings of the register. In case the wheel f, &c., is already recording its highest number 9 the pin f5 will strike a shoulder g5 of the wheel g, &c., thus moving the latter the distance of a thereon, which motion will be again transferred to the succeeding wheel f', 495e., moving theA latter the distance of a recess f4 and causing a correspondingly-higher number on such wheel to appear under the slot h of the cover. It will thus be seen that one revolution of one of the wheels f,f, or f2 means.

one-tenth of a revolution of the succeeding wheelf, f2, or f3, and that the numbers on the first wheel f designate units, on the second .'f tens, on the third f2 hundreds, and on the fourth f3 thousands, and .that by the pin g4' above-described arrangement of wheels I can record nine thousand ninehundred and ninety-nine unlockings.

In Fig. 3 I have represented as an additional safeguard a key-lock, in which case I represents a post to receive the barrel of-a key, which when partially turned will strike the dog t', forcing it into the notch t" in the bolt B, locking the latter in position, while if the key is still further turned it will strike the arm 2 of the pawl 3, and thus, by means of the arms i4 and 5 on the pawl yand dog respectively, withdraw the lat-ter from the bolt and unlock it. In this-figure, and in Fig. 4 also, a spring trip-lever J is applied directly to the lug 127 on the bolt instead of being attached to the slide E, and serves the same purpose as the trip-lever e3.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination, with a slidingbolt having an open slot therein adapted to receive a seal, of means for preventing the forward movement thereof, a trip-lever actuated by the bolt, and a registering mechanism driven by the said trip-lever, as described.

2. The combination, with a suitable casing, of a sliding bolt having an open slottherein and a projection thereon in the interior of the casing, pivoted dogs engaging the said projection, springs attached to the said dogs throwing their nosesbehind their pivotal points, a slide carrying a trip-lever actuated by the bolt, and wheels having numbers therein actuated by the trip-lever, as described.

3. The combination', withaslidingbolt having a slot therein and a projection thereon, of spring-dogs engaging the said projection, an independent slide having projections upon its forward and rear ends and carrying a triplever, and a registering device driven by the said trip-lever, as described. A

4. The combination, with a sliding bolt having an open slot therein and a projection thereon, a spring-actuated dog engaging the said projection on the sliding bolt, a trip-1ever actuated by the backward movement of the said bolt, and a registering device actuated by the said trip-lever, as described.

5. The combination, with a locking-bolt having a slot therein, of a seal contained in the said slot, a post upon the said bolt, dogs preventing the forward movement of the said post, a trip-lever actuated by the said bolt, and a registering device driven by the said trip-lever, as and for the purposes described.

In testimony whereof I have atlixed my signature in presence of two witnesses.

WILLIAM FESSENDEN BEASLEY.
